Hi Gresham
I can say you exactly what is in my products , but i hope it is understandable that i cannot say the ammount of each element and which "protecting" material i use to hold the goods in solution.
You said all have to declare like the food industry do
i was also several time in the states but i never see how much.
Trace Elements and genetic changed proteins was in my Milk or
how many pesticides in my Orange ??
We use for the balling light elements a very old receipt which was developed around the year 1984 , we changed the receipt over the years cause the experience of thousands of reefers and our tests showed this over the years.
The base of the Trace Elements is the coral grow and that what corals need to grow. all that is in the elements solution , without unwanted elements in.
all salts are very high purity and this protect unwanted algea grow.
In this system, the consumption of calcium and alk the base of the dosage. calculated by the remaining trace elements which are needed by the coral for the growth or which the coral can store, based on the level of natural seawater.
Then you need to compare the ionic inbalance. That we said on balling light to make a weekly waterchange has a very simple reason
1. A regular water change is always the best methode to keep a tank stabil
2. due to the waterchange you automatical check your salinity and then it is easy to set up the right level.
If you have a tank in old style version , which means slightly yellow water, big Soft corals some higher algeas and a heavy fish load you will and you cannot see the difference in the quality of the salts and solutions. In modern reef tanks with SPS , LPS , high power lighting, skimming and bright corals you can see this very fast. many people which have problems with unwanted algea grow, Cyanobacterias add to much and the wrong elements in their tank, cause the use the chaepest possible salts to control the water parameters
It has a reason why european reefers use the balling methode for so many years with great succes. Their long time experience in coral keeping showed this.
